> Lookahead assertions have been part of JavaScript’s regular expression syntax from the start. Their counterpart, lookbehind assertions, are finally being introduced. Some of you may remember that this has been part of V8 for quite some time already. We even use lookbehind asserts under the hood to implement the Unicode flag specified in ES2015.
@ASCII-only Looking at my browser history, I spent about 9 minutes on #7. I spent the longest on #12, at around 11 minutes. It was frustrating, because I saw easy solutions that used lookbehinds, but those weren't allowed.
I am a novice in complexity calculation. I need to calculate the overall time complexity.
My attempt is given below:
Here, N = number of data points (N>300), C = Number of clusters (2<C<30)
For line 3 to 10, time complexity, TC1 = O(NC)
For line 11 to 12, time complexity, TC2 = O(C)
For lin...
There's a satirical song called Little Boxes, originally by Malvina Reynolds, about suburban sprawl that has lyrics as follows:
Little boxes on the hillside,
Little boxes made of ticky-tacky,
Little boxes on the hillside,
Little boxes all the same.
There's a green one and a pink one

I need to go to the bank and withdraw some money. I need to withdraw $30, $22 to pay my roommate for the internet and $8 for laundry. Since neither of these can make change, I need my $30 to be split into two partitions of the two sizes. That means when the teller asks me how I want my $30 I a...
CMC: Given n, convert n to hexadecimal, using the hex digits. Examples: 100 => 64, 1523 => 5F3 You may use either upper or lowercase letters. The output may not be preceded by 0x.
Introduction
Problems where a language has to compute something about itself are often fun and insightful. This is a simple statistical insight problem. It is also a problem on how easy a language can poke at its own architecture. When one codes in a specific language, a specific vocabulary is u...
That's my question. PowerShell has keywords, reserved words (which overlaps with keywords but has a couple differences), aliases, cmdlets, can run CMD commands and aliases, everything in the Resource Kits, etc. Where's the line drawn?
Your task is to take in one integer input and print a zigzag pattern using slashes and backslashes.
The integer input determines the length of each zig and zag, as well as the number of zigs and zags
The pattern always starts from right to left

What does the Python nonlocal statement do (in Python 3.0 and later)?
There's no documentation on the official Python website and help("nonlocal") does not work, either.
PowerShell has global, script, private, local, and numbered scopes. But the numbering is weird. 0 is current scope, 1 is parent, 2 is grandparent, etc.
